ROTATABLE PERFORATED TOP WITH AGITATOR FOR POWDER CANS Filed Oct. 29, 1946 Patented Mar. 20, 1951 OFFICE ROTATABLE PERFORATED TOP WITH AGITATOR FOR POWDER CANS 7 John J. Mackert, Detroit, Mich. Application October 29, 1946, Serial No. 706,381

4 Claims.

This invention relates to rotatable perforated top with agitator for powder cans, especially designed for containing tooth powder or the like, the primary object of the invention being to provide a powder can having a rotatable top provided with means for agitating the powder at the discharge opening of the top, to prevent the powder from caking at the discharge, opening,

and becoming so solidified that th powder will not move through the discharge opening.

An important object of the invention is to provide an agitator of this character which is so constructed and arranged that with each rotary movement of the cover to open the discharge openingof the can, the agitator will loosen and direct a quantity of powder forwardly, to the discharge opening.

Another object of the invention is to provide a cover of this character which may be manufactured at a minimum cost and without increas- Figure 1 is a plan view of a powder can equipped with the cover and cap, constructed in accordance with the invention.

Figure 2 is a bottom plan view thereof, a portion of the agitator blade having been broken away, illustrating the construction of the pivot of the rotary cap. 7

Figure 3 is a sectional view taken on line 3-3 of Figure 1. y

Figure 4 is a sectional view taken on line 44 of Figure 1.

Referring to the drawing in detail, the reference character 5 indicates a tooth powder can which is formed with a raised spout 6 which is closed with the exception of the discharge opening 1 and the central openin 8, through which the strap 9 of the inner rotary section II] extends. The inner rotary section It] is formed with an annular flange II which is cut away as at l2, the cut away portion l2 extending an appreciable distance into the main portion of the inner rotary sect on III, providing a discharge opening, adapted to register with the discharge opening of the spout 6 2 for permitting powder to pass from the through the discharge opening.

Formed integral with the inner rotary section I0, is an agitating blade l3 which is sub stantially triangular in shape, the blade being wide to out under the powder which i delivered within the spout, for discharge through the (118+ charge opening of the can.

As clearly shown by Figure 3 of the drawing, this agitat ng blade l3 extends towards'theinner rotary section,'the free edge of the blade being disposed at a point adjacent to the discharge opening I, the blade being inclined with respect to the annular flange I I.

Cooperating with the inner rotary section II), is an operating disc 14 which is formed with a finger I5 that fits under the strap 9 which is struck from the rotary section II] and bent upwardly out of its plane, where it is extended .can

through the opening 8 in a position to receive the finger l5 securing the operating disc l4 and the inner rotary section l0, together, so that rotary movement of the operatng disc M, will rotate the section Hi to align the opening of the inner rotary section In with the discharge opening 7. 4

The segmental flange I6 is formed on the operating disc, and this flange is formed with a roughened surface to permit easy operation of the operating disc [4, when the finger of the person using the can, is moved over the flange I6.

From the foregoing, it will be seen that due to the construction shown and described, with each movement of the operating disc H! or cover, to align the openings of the rotary section and the spouts, the agitating blade It will not only agitate the powder which collects within the spout, maintaining the powder loose, but will at the same time act to direct a quantity of the powder towards the registering openings where it may pass from the can.

What is claimed is:

1. In a powder can, a spout having a discharge opening, a closure for the spout, said closure comprising an inner rotary section having an opening adapted to register with the discharge opening of the spout, and a substantially triangular inclined agitator blade connected at one of its ends with the inner rotary section the opposite end of the blade being free and adapted to pick up and direct the .powder towards the discharge opening as the inner section is rotated, and means for rotating the inner rotary section and blade.

2. In a powder can, a spout having a discharge opening, an inner rotary member mounted within the spout and having a discharge opening adapted to register with the opening of the spout permitting material to pass from the can, an operating disc mounted exteriorly of the spout and having connection with the inner rotary member whereby rotary movement of the operating disc operates the inner rotary member, and an agitating blade inclined with respect to the rotary member mounted on the inner rotary member at one end of the blade, the opposite end of the blade being free and adapted to cut into the material Within the can and agitate material adjacent to the discharge opening.

3. In a powder can, a spout having a closed outer end formed with a discharge opening and having a central opening, an inner rotary member mounted within the spout, va strap formed on the inner rotary member and being extended through the central opening of the spout, an operating disc mounted on the spout, a finger eX- tending from the operating disc and adapted to be positioned within the strap or the inner rotary member, securing the operating disc and inner rotary member together, whereby movement of the operating disc operates the inner rotary memher, and a blade carried by the inner rotary membee, said blade being inclined and adapted to direct powder toward the discharge opening, when the operating disc and inner rotary memher are rotated.

4. 'In a powder can, a spout having a discharge opening, an inner rotary member mounted within the spout and having an opening adapted to register with the discharge opening of the spout, permitting material to discharge from the can, an operating disc mounted on the spout and having a segmental flange extending downwardly therefrom, providing a finger piece, means for connecting the inner rotary member and operating disc whereby movement of the operating disc rotates the inner rotary'member, and an inclined agitating blade secured to the inner rotary member at one end of the blade and operating adjacent to the discharge opening the opposite end of the blade being free and inclined towards the rotary member adapted to pick up material and direct material to the discharge opening as the inner rotary member is rotated.
